Immunology Consultants anti-Hamster (CHO) Matrix metalloproteinase-19 Antibody - Affinity Purified
This affinity‑purified antibody targets hamster (CHO) Matrix Metalloproteinase‑19 (MMP‑19), an extracellular protease associated with matrix remodeling, cell migration, and tissue‑level structural regulation. Designed for sensitive detection of CHO‑derived MMP‑19, it supports applications in host cell protein profiling, bioprocess impurity monitoring, and characterization of recombinant protein production systems. The chicken‑derived format minimizes interference from mammalian proteins, delivering clean, reliable performance in ELISA, Western blotting, and orthogonal analytical methods. Its high specificity and consistent purification make it a valuable tool for laboratories requiring dependable detection of low‑abundance CHO process‑related proteins.
